The N1 plays really loud so it will sound great in pretty much any room. That said, it comes with external subwoofer connectivity so no room is too big a challenge.
While I’m not familiar with your desk top most have a few different audio outputs so yes you should be able to connect the N1 to your desk top.
Hello,
This is Gary from Polk, I actually have my N1 connected to my desktop. If it is a desktop with a good motherboard sound chip or if you have a sound card, you can just use an optical connection.
Thanks,
